T-bills average return = 39.31% / 6 U. T-bills average return = 6.55% V. b. Using the equation for variance‚ we find the variance for large company stocks over this period was: Variance = 1/5[(–.1469 – .0324)2 + (–.2647 – .0324)2 + (.3723 – .0324)2 + (.2393 – .0324)2 + (–.0716 – .0324)2 + (.0657 – .0324)2] Variance = 0.058136 And the standard deviation for large company stocks over this period was:

this case the four scores for PD‚ UAV‚ IND and MAS. Vi is the variance of the score of this dimensions. The variances for all dimensions can be calculated in excel. 2. What is the difference between mean and variance? Can you explain the example given in the lecture in your own words? The mean is a weighted average of the possible values a certain variable can take. The mean provides the long-run average of a variable. The variance of a variable measures the spread or variability of the distribution

Covariance of two securities measures their co-movement. How do we Calculate Co-variance? There are three steps involved I the calculation of covariance between two securities; Determine the expected returns for securities Determine the deviation of possible returns from the expected return for each security.
